Narynia setosa Martynova, 1967

Figs 1, 4 , 5 , 9 .

Material. Holotype and paratype, Kyrgyzstan, Inner Tien Shan Mts, upper flow of Bystriy Naryn River, desert, (3000–3200 m alt.), 12.VIII.1965, leg. R. Zlotin ( ZIN).

Additions to description. Ant.2 with 4 bms (two bms set instead of one on the inner side of the segment) on one side of the holotype and on both sides of the paratype. Ant.3 with one bms and 5 sensilla (including one lateral). Ventral side of a head with 3+3 postlabial chaetae. Axial chaetae on Th. III 7–8, on Abd. I–III 4–5 (each segment). Macrochaetae 11/2234, Md on Abd.III hardly developed. Tergal macrosensilla much shorter than ordinary chaetae. Macrosensilla on Abd.I–III located between Mdl and Ml ( Fig. 5 ). Abd.V with medial sensilla much longer than lateral sensilla, inserted far from each other ( Fig. 9 ). Sternum of Th.III with 2–3+2– 3 chaetae. Ti.1–3 with 21, 21, 24 chaetae respectively. Ventral tube with 4+4 laterodistal and 4–5 caudal chaetae. Tenaculum with 3+3 teeth and one chaeta. Dens with 3 anterior subapical chaetae and 5 unequal posterior chaetae ( Fig. 4 ).

Remarks. The many setae on dens and very long medial sensilla on Abd.V define this species. Distribution. Known only from the type locality.
